Q

What is the indicator that you need to use antibiotics peri-operative prophylactic antibiotics?

A
  • Risk of infection
  • Development of SSI would be catastrophic
17
Q

What is the suggested use of peri-operative prophylactic antibiotics?

A
  • Clean-contaminated, contaminated and dirty procedures
  • Clean orthopaedic procedures
18
Q

What are peri-operative prophylactic antibiotics?

A
  • Intravenous
  • Broad spectrum of antibiotics
  • Use 30 minutes prior to incision
19
Q

What antiseptic should not be used in ears?

A

Chlorrhexadine

20
Q

Why should you handle tissue gently?

A
  • Uninjured tissue takes 106 bacteria per g for infection to be established
  • Injured/crushed tissue takes 103
21
Q

Why do you need to be meticulous with haemostasis?

A
  • Better perfusion = Better handling
  • Better visualisation for the surgeon
  • Clots in the surgical field are the perfect medium for bacterial growth
22
Q

What is the best way to preserve the blood supply?

A

Do not ligate any major vessels

23
Q

What is the function of perfusion?

A

Delivery of O2, Leukocytes and inflammatory proteins to healing tissues

24
Q

What is the function of eliminating dead space?

- by suturing

A
  • Reduces wound fluid accumulation
  • allows tissue sealing to occur earlier
  • lower risk of seroma/ abscessation less tension on the wound
25
Q

What is the function of accurate tissue apposition?

A
  • Aids and speeds healing
  • Particularly important where leak proofing is neccesary
  • Improved functional results
26
Q

Why do you need to minimise tension on tissues?

A

Tension on tissues causes capillaries to collapse

27
Q

How long does the fibrin seal last for?

A

6 hours
* waterproof but can be easily disrupted

28
Q

How can the fibrin seal be disrupted?

A
  • Tension
  • Movement
  • Licking
  • Handling of the patient
29
Q

What are two ways you can help reduce wound contamination?

A
  • apply the barrier in an aseptic manner, whilst in theatre
  • maintain the barrier carefully in hospital
30
Q

What is a nosocomical infection?

A

Infection acquired within a hospital setting

31
Q

How do you reduce Horizontal transmission

A
  • Keep wound covered
  • Hand hygeine before touching the patient
32
Q

How do you reduce vertical transmission?

A
  • Routine hospital cleaning
  • Protocols
33
Q

How would you treat SSI if theres no systemic signs?

A
  • Treat as a traumatic infected wound
  • swab for culture and sensitivity
  • Broad spectrum pending results
34
Q

How would you treat an SSI if it is septic?

A
  • Aggressive treatment
  • IVFT, antibiotics, analgesia
  • Surgery once stable for GA
